Answer
a. C is the limiting reactant in this reaction.
b. Mg is the limiting reactant.
c. Hydrogen is the limiting reactant of Haber process.
Work Step by Step
a. When you burn charcoal in the burner, the reactant you add to the reaction is C while oxygen comes from the air. Therefore C is the limiting reactant in this reaction.
b. Water can easily be found in planet earth, while Mg is not so easily found. The industrial processes to produce pure Mg are far more expenses than the processes to produce water. Therefore Mg is the limiting reactant.
c. More than 78% of Earth's atmosphere is calculated to be nitrogen gas., while hydrogen percentage of Earth's atmosphere is less than 1%. Therefore hydrogen is the limiting reactant of Haber process.
